Lentigo maligna is a histopathological variant of melanoma in situ. [6] Lentigo maligna is sometimes classified as a very early melanoma, [7] and sometimes as a precursor to melanoma. [8] When malignant melanocytes from a lentigo maligna have invaded below the epidermis, the condition is termed lentigo maligna melanoma. [2]
Other benign skin lesions that may mimic acral lentiginous melanoma include: Lentigo (sun spots), Acral Nevi (moles), or Onychomycosis (fungal infection of the nail). These skin lesions can appear as dark brown spots, like ALM, but can be distinguished on close examination or dermatoscopy. [7]
Lentigo maligna is the non-invasive skin growth that some pathologists consider to be a melanoma-in-situ. [3] A few pathologists do not consider lentigo maligna to be a melanoma at all, but a precursor to melanomas. Once a lentigo maligna becomes a lentigo maligna melanoma, it is treated as if it were an invasive melanoma.
A meta-analysis of the literature in 2014 found no randomized controlled trials of surgical interventions to treat lentigo maligna or melanoma in-situ, even though surgery is the most widely used treatment. [144] Mohs surgery has been done with cure rate reported to be as low as 77%, [109] and as high as 95% by another author. [110]
A lentigo (/ l ɛ n ˈ t aɪ ɡ oʊ /) (plural lentigines, / l ɛ n ˈ t ɪ dʒ ɪ n iː z /) is a small pigmented spot on the skin with a clearly defined edge, surrounded by normal-appearing skin. It is a harmless (benign) hyperplasia of melanocytes which is linear in its spread.
Superficial spreading melanoma (SSM) is a type of skin cancer that typically starts as an irregularly edged dark spot typically on sun-exposed part of the body. [2] [3] The colour may be variable with dark, light and reddish shades; occasionally no color at all. [2]

Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. [1]: 696 [2] They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly.
